Why don't you use a solar-powered laptop? I don't

because I don't go outside and I'd rather have a solar powered air conditioner

>>43293300
Look at all that power inneficiency
>solar to 12v to 120v to 19v
Most power would've lost as heat in that setup.

>using laptops outside

Because I've got a laptop that lasts 12 hours on a single charge and it charges fast as fuck.

Guess the laptop, /g/!

>>43293392
I would've said the Air, but I used those a while back and they are slow as fuck because of the shitty ULV i5 even with an SSD...
So I say a Thinkpad!

Actually have wanted to get a solar panel like that for a while now.

Anyone know one that could actually charge a laptop? Or have guides on building one?

I've been running my laptop directly off a solar panel for a while, 20v panel>12v boat battery>20v laptop. Not the best setup but it works, feels good man. Btw it's a thinkpad.

>>43293453
How much did the solar panel cost? Have a link to where you got it?

>>43293392
An ARM powered chromebook?

>>43293408
>>43293491
It's a Macbook Air!

>>43293300
Because consumer solars are still have, like, 15% efficfiency and overpriced as fuck. Oh, and BTW, I don't use laptop outside I prefer using it on a desk.

If I wanted to work long time outside, I'd try to fit a raspberry pi, a kindle and a mechanical keyboard into a case.

>>43294137
>>43294156
even if it was just like a terminal+simple editor.

I am look at the monitors they used to code on.

I just don't think the interests there though.

As said there's some e-ink tablets, but they seem to be Chinese only and locked in to mobile OS.

>>43294178
Go be a fag somewhere else, no one wants your overpriced shitbook.

>>43294201
I'm going to look around and see if I can find one of the screens for sale somewhere else. If I can get a screen and hook it up to something which barely draws any power, like an Arduino or Raspberry Pi, it would work great

>>43294013
I would buy something netbook-sized with eink screen. As log as it is not a fucking tablet, I think it'll have its market.

>>43294197
No, it lives in my garage.

For portability, I use an AC inverter in my truck.

Oh, someone already did it? How did they hook the Raspberry Pi up to the display? Link to the article, if possible.

>>43294251

Not the keyboard I would use...

Actually, is there any way to get a bigger e-ink display than the kindle ?

>>43294251
I hate you m8. You made me wanting that. As if wanting to buy RPi just for lulz is not enough.

>>43294292

>>43294293
There's been some e-ink attempts by indivduals/small groups.

Buy they always end up in production hell, and always obsolete, overpriced, and too late, like that pandora game console thing.

I'd just use a fucking USB keyboard.

>>43294292

Just contacted the eink company, inquiring about 10-14 inch screens and their prices. They apparently offer them up to 20+ inches! Imagine having a full desktop screen in eink, haha.

>>43294394

Since they likely don't have any major hardware assembler ordering it, I'm afraid it's gonna come up really expansive.

You can actually run native linux software on Kobo ereaders, I've installed full busybox, python and qt without even opening it up.
There are also some models that have Usb OTG, so yay!

Here in Italy there are a couple of houses that use solar panels to live off the grid.
They actually don't live off the grid, they are still connected to the electrical company to sell them electricity they don't use.

>>43294660
By "here in italy there are a couple of houses" i meant "near me there are a couple of houses".
Fucking thinking in Italian.

>>43294660
That's pretty cool, it would be nice to have no electricity bill PLUS actually getting money each year just from living with solar panels.

>>43294660
We're going to reach a point in the future where a majority of homes are solar powered, so much so that they generate enough power for everyone.
And because of the way we're doing things now, the power companies are still going to exist, not producing their own power, and just buying excess power from solar homes and selling it for twice the price to non-solar homes

>>43294723
Also, power companies here literally gift solar panels, or make you pay only the installation.

>>43294773
Will not happen in Siberia where I live. ~70% of year's time theres not enough "sun" for solars to be reliable.

>>43294843
Whoa

Siberia has internet?

>>43294856
Yep. The internet came here about 16 years ago.

>>43294843
Does Siberia have a lot of flat ground or wind? You could always try wind power

>>43294843

You could always try fossil fuel power

Kobo Aura HD is $169 and is 6.8 inch and 1440×1080 with 265ppi. I bought one yesterday for textbook PDF's. I don't know how usable it is as a laptop, but the kobo firmware is on github:

i used a rooted Nook Touch with a keyboard for a while for IRC. I had a T-nut epoxied to the back that I attached to a camera mount, and I had a chopped up USB cable for backfeeding power so I could have the keyboard connected and charge it at the same time.

I guess you could just run screen and do everything else from some remote AWS instance, but I got bored of it quickly.

That was big news a few years back. That lady who was with one laptop per child made a display that was supposed to have the characteristics of lcd and e-ink. Massive power cut. Guess it didn't work out.

The resolution is too hard to really tell, but I still think it is dc to dc like this pic. Most people would probably think the thing it is plugged into is an inverter. Though if it is, then it has to be a European plug.

There is no AC here, I think you're seeing the air pump and an AC inverter.

that is quite possibly the most autistic thing i've seen all day

Why is everyone assuming you would use this setup for outdoor use only? Just install the fucking panel on your roof or wherever and run a cable into your house. Probably save a shit ton of money.

In Arizona, the local power company used to have an incentives program for homeowners installing solar power.

So many people used this, and made so much money selling power back to the grid, that the power company had to stop the incentives program and is now charging a monthly fee for new installations that get plugged into the grid.

>mfw solar power is still profitable even with the fee

>>43303419
In Italy it works like that, but obviously your electricity it's worth almost anything to the electric company.

The resolution is too low to tell if that thing is an inverter or an adapter that is part of a dc to dc converter and the link you posted is a different product.

>>43303419
Yeah, the thing about that is when you get enough solar penetration on the grid it fucks things up during peak solar hours. They have to take power from renewable sources like solar and wind first even if they don't need it and pay out mandated rates to these people so they have to pay to have a surplus of power they can't use. They sometimes end up paying businesses that use a lot of power money to burn as much as possible at peak generation hours.

What really sucks is that peak usages often comes later in the evening when solar power is rapidly falling off. This is where they need the inefficient single cycle gas plants to ramp up production fast enough to keep from having brownouts and the like in the evening.
